PRIORITY

This patent application is a continuation of U.S. patent application of U.S. patent application Ser. No. 12/882,196, filed on Sep. 14, 2010 in the name of the same inventor and entitled “Bottom Loading Paintball Feed System,” hereby incorporated into the present application by reference.

FIELD

The present invention relates to paintball markers. More specifically, the present invention relates to paintball feed systems.

BACKGROUND

With increasing popularity of paintball tournaments as well as professional trainings such as military and sporting practice, more accurate and realistic looking paintball guns or markers are in demand. For example, the success of training or competition depends on how quickly an operator of a paintball marker can eliminate opponents by hitting them with paintballs or paint projectiles. A problem associated with a conventional paintball marker or gun is that the accuracy of paintball marker is relatively poor partially due to the traditional design of the paintball guns or markers.

A conventional paintball gun or marker, for example, typically loads paintballs from a hopper into the paintball gun via a gravitational force. The hopper, which is mounted on the top of paintball guns or receiver, typically obstructs aiming capability of an operator. An operator usually has a difficult time taking proper aim via a front sight on the barrel.

Another problem associated with a conventional paintball marker or gun with a hopper mounted on top of the receiver is that a typical paintball gun deviates from a real gun whereby using paintball marker as training exercise degrades the effectiveness of military and/or police field training.

A bottom feed magazine is a paintball ammunition storage and is capable of coupling to a paintball marker for loading paintballs to the marker for repetitive propelling of paintballs. Paintballs are considered as ammunition for the paintball gun or marker and they, for example, are round or spherical shaped capsules containing dye substances. Upon an impact of a paintball, the paintball leaves a colored marker. Magazines, for example, can be fixed or removable from paintball markers, wherein a magazine can be an integral part of paintball markers. Alternatively, a magazine may be removable from a paintball marker. Note that datable bottom feed magazine may also be referred to as a magazine clip.

A function of bottom feed magazine is to transfer paintballs stored in the magazine into a place or chamber of a receiver whereby the paintballs can be loaded and/or launched. Receiver of a paintball marker can also be referred to as an assembly, body, or frame which is a part of physical structure that houses various mechanical and/or operating parts or components. The terms “receiver,” “body,” “assembly,” and “frame” are hereinafter used interchangeably.
